When rtl8192ce is in operation, kmemleak indicates a number of leaks, yet when the driver is removed all are gone.

The background scan completion takes more time when the station is having heavy uplink traffic. The scan state machine decides to fall back to home channel on every off-channel visit when there are pending frames in tx queue. bgscan completion took ~30sec on dual band US regulatory card. scan period = (20 active channels * probe timeout) + (12 passive channels * passive probe timeout) + (32 * timeout on home channel) + (32 * flush timeout) Signed-off-by: -

Sync-up ibss beacon timer with the beacon frame's timestamp. When the node acts as joiner, it has to sync with the received beacon timestamp instead of reading tsf from hw. As the hw tsf wont wont be update till bssid is configured. This patch programs hw tsf with the received beacon timestamp if beacon timers are yet to be configured. Signed-off-by:

When testing mesh synchronization we observed a global TSF slowdown that was dependent on the number of synchronized mesh stations. This seems to be caused by the TSF adjustment (read/write) latency. Adding a small margin to the Toffset setpoint solved the problem. Signed-off-by:

Commit 3a25a8c8 (mac80211: add improved HW queue control) introduced a bug when running in AP mode without the IEEE80211_HW_QUEUE_CONTROL flag set. The ieee80211_check_queues() function always returns -EINVAL, preventing AP mode from starting. To fix this, check whether this flag is set before checking if cab_queue is set properly.

My grand plan to allow drivers to gradually move over to advertising virtual interface combinations and only enforce with drivers that do want it enforced doesn't seem to be working out, only Christian ever added the advertising (to carl9170), nobody else did. Begin enforcing combinations in cfg80211 so that users can rely on the information reported about a device. Cc: "Luis R.

The driver provides a regulatory hint to cfg80211 as obtained from the SPROM. Mostly, this will be a two-letter ISO country code. However, it may obtain special country code similar to the world regulatory domain as used in cfg80211. This patch avoids setting these special codes as the hint is lost to cfg80211. Reviewed-by:

The brcmsmac driver provides the country code from sprom as a regulatory hint to cfg80211. When brcmsmac does not find a country code entry in the sprom it passes 'US' as regulatory hint. Better approach is to rely on the world regulatory domain in cfg80211/crda. Reviewed-by:

The MAX_TXPWR table for BTCOEX is not needed for AR9462. Programming these values to the HW results in undesirable behavior - for example, large number of delimiter/data underruns are seen in AES-CCMP mode. Also, registers like AR_PCU_MISC_MODE2 return 0xdeadbeef after the BTCOEX_MAX power table is programmed to the HW, and frames being transmitted end up being looped back to the RX engine, an example being beacon frames in IBSS mode. Remove this table for now - this fixes CCMP performance and general IBSS usage. Signed-off-by:

I noticed a possible issue in the status count field management of the ieee80211_tx_info data structure. In particular, when the AGGR processing is employed, status.rates[].count is set just for the first frame and not for others belonging to the same burst, leading to wrong statistic data in the mac80211 debug file system.
